God commanded nations and peoples to spread out across the whole earth.
This plan was established in the beginning. According to the Genesis record of God and His dealings with men. So that men would spread out and live happily within “the bounds of their habitation.” (Acts 17:26)
No nation or people has ever existed outside of the influence of God.
Meaning, that every nation knows what is right and what is wrong. This has always been the case. Even with those tribes that have existed in the most remote corners of the world.
But this is not a popular belief.
